As a first step in improving compatibility between JSCS and ESLint, we need to identify the gaps between JSCS rules and ESLint rules. Polyjuice had done some initial analysis that can be found here: https://github.com/brenolf/polyjuice/blob/master/doc/JSCS.md (this is a list of rules and options that ESLint doesn't cover).

I'm not sure what other changes have happened or what version Polyjuice was referring to, so we probably need to double-check that information and see if there are any other gaps.

Let's use this issue to build up a list of missing rules and missing rule options, and then we can file separate issues to implement each of the missing things.
